In this paper, the authors extend the Reliability Constrained Cost Minimization (RCCM) model by the researchers from two view-points: time non-homogeneous property on software failure-occurrence process and gap between testing and operational phases of software product. The expected cost minimization with reliability constraint is formulated as a non-linear minimization problem under alternative scenario on the operation. They develop an effective optimization algorithm based on the Kuhn-Tucker conditions and provide an illustrative example on how to design component-based software.
